The determination of sulphur in lubricating oil fractions and in fuel oils—a coulometric method

Abstract

The original combustion-microcoulometric method in which the Dohrmann microcoulometer is used for the determination of trace amounts of sulphur in organic liquids has been modified. The inlet to the microcoulometer has been re-designed to permit complete combustion of oils to take place in the inlet. The modified inlet and flow systems have been used for the determination of sulphur in oil fractions obtained from preparative layer chromatography and in fuel oils.
